Polydactyly is the most common aesthetic hand anomaly. Its surgical correction is indicated for aesthetic, but especially for functional reasons. Independent of the degree and location (pre- or postaxial) of the anomaly the creation of one single unit, which corresponds to the functional as well as to the cosmetical demands is the main purpose of the operative correction. The principle of this operative procedure is the fusion of the two fingers by using all existent structures. Therefore and due to the individuality of each case of polydactyly only after clear exposure identification of soft tissue structures is possible. Resecting procedures of bony and soft tissue structures which are performed before the fusion shall therefore be performed after the exposure and by preservation of all structures, which are necessary for growth, function, sensibility and blood supply. Using these principles clinical experiences which were made with this method are demonstrated while also postoperative results are shown.  相似文献

The management of young patients with severe hip arthritis is very difficult, as treatment options, such as total hip arthroplasty, which is excellent for relieving pain while preserving function, are often avoided because of a high requirement for subsequent revision surgeries. Hip arthrodesis, although perceived as having inferior functional outcomes in these young individuals, offers a treatment option that relieves pain, maintains function, and allows for conversion to a total hip arthroplasty in future, if desired. This article reviews the indications and technique of hip fusion.  相似文献

BackgroundThere are few studies about risk factors for poor outcomes from multi-level lumbar posterolateral fusion limited to three or four level lumbar posterolateral fusions. The purpose of this study was to analyze the outcomes of multi-level lumbar posterolateral fusion and to search for possible risk factors for poor surgical outcomes.MethodsWe retrospectively analyzed 37 consecutive patients who underwent multi-level lumbar or lumbosacral posterolateral fusion with posterior instrumentation. The outcomes were deemed either ''good'' or ''bad'' based on clinical and radiological results. Many demographic and radiological factors were analyzed to examine potential risk factors for poor outcomes. Student t-test, Fisher exact test, and the chi-square test were used based on the nature of the variables. Multiple logistic regression analysis was used to exclude confounding factors.ResultsTwenty cases showed a good outcome (group A, 54.1%) and 17 cases showed a bad outcome (group B, 45.9%). The overall fusion rate was 70.3%. The revision procedures (group A: 1/20, 5.0%; group B: 4/17, 23.5%), proximal fusion to L2 (group A: 5/20, 25.0%; group B: 10/17, 58.8%), and severity of stenosis (group A: 12/19, 63.3%; group B: 3/11, 27.3%) were adopted as possible related factors to the outcome in univariate analysis. Multiple logistic regression analysis revealed that only the proximal fusion level (superior instrumented vertebra, SIV) was a significant risk factor. The cases in which SIV was L2 showed inferior outcomes than those in which SIV was L3. The odds ratio was 6.562 (95% confidence interval, 1.259 to 34.203).ConclusionsThe overall outcome of multi-level lumbar or lumbosacral posterolateral fusion was not as high as we had hoped it would be. Whether the SIV was L2 or L3 was the only significant risk factor identified for poor outcomes in multi-level lumbar or lumbosacral posterolateral fusion in the current study. Thus, the authors recommend that proximal fusion levels be carefully determined when multi-level lumbar fusions are considered.  相似文献
